[TerkinData] Add separate PlatformIO environment native-radiohead

Fixes compilation on Linux.

__unix__ is defined on Linux, while __APPLE__ is defined on macOS [1].
In the default configuration, we don't want to specialize for any of
both.

It is probably a leftover from where we explored simulating RadioHead-
based code.
